. IMPR'QVEMENT IN METALLIC ABUTMENTS FOR BRIDGES.4

The Sthodule referred to these Letters Patent and making part of thesame.'

Be it known that I, ALPHEUS WHEELOCK, ot Fort Wayne. in the count-'y ofAllen, and State of I ndiaua, have invented a. new and useiulImprovement in Metullio Abutments for Bridges; and l do hereby declarevthat the following is a full, clear,and exactl description of theconstruction and opera-tion ot' the sume, reference being 'l1ad.to theaccompanying drawings making a part of this specification, in which-Figure 1 represents a. plan view.

Figure 2 represents a front elevation.

'This invention relates to a metallic Yabutment for bridges, constructedin a'novel and improved manner, as will hereinafter more fully appear.

In the. drawings- A A- represent uptight metallic columns, cast ofsolidv metal, in the form seen in tig. 1, a'nd secured together insections of a suitable length, as seen at a, by means of anges and boltsThe outer sides of the columns stand in' the same vertical planes withthe adjacent sides of the abutment.

The tops and bottoms of the columns are provided with suitable tlanges,b b', for the purpose of forming a suitable bed for the reception of,the bridge, and a suitable base upon which the abutmentma-yrcst.

B brepresents another column, whichis connected in the form seen in iig.l, and is placed equidistant between the collnnns A A.

0.0 O O represent other columns, which are placed as seen in thedrawings, aud are provided with tianges c.

D D represent metallic plates, which are constructed oblong iu form, andare each provided with two ribs, d, which extend nearly the entireleugthofthe plates.

These ribs are vfor the purpose of giving strength and F is a brace,which connects the intermediate set of A side columns C C, for the samepurpose.

G G represent braces, which extend from the inner 'corners otl the'abutment to the column marked B,

where they are secured, as seen in fig. 1. These rods or braces are allprovided with swivels, for the purpose ot' tightening them.

H H represent other braces, which connect the centers of the plates D,for the purpose of supporting them against outward pressure.

The plates D are rabbeted, so that the lower edge I b'e extended abovetheir tops, and thus form a resting n place for the chords of thebridge.'

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

The construction herein described, consisting of the hollow cornercolumns A, to be filled with cement, the side columnG, braces E G, andribbed plates D, all forming a hollow abutment, which may be filled withsuitable material, as and for the object specified.
